Fields across Europe are contaminated with dangerous levels of the antibiotics(抗生素)given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food and water, helping to create a new generation of antibiotic-resistant "superbugs(超级病菌)" The warning comes from a researcher in Switzerland who looked at levels of the drugs in farm slurry(泥浆). 【R1】______
Some 20,000 tons antibiotics are used in the European Union and the US each year. More than half are given to farm-animals to prevent disease and promote growth.【R2】______.
Most researchers assumed that humans become infected with the resistant strains(耐药菌株)by eating contaminated meat. But far more of the drugs end up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute for Environmental Science and Technology in Dubendorf. 【R3】______
With millions of tons animals manure spread onto fields of crops such as wheat and barley each year, this pathway seems an equally likely route for spreading resistance, he said. The drugs contaminate the crops, which are then eaten. 【R4】______
Mueller is particularly concerned about a group of antibiotics called sulphonamides.【R5】______. This concentration is high enough to trigger the development of resistance among bacteria. But vets are not treating the issue seriously.
There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted(排泄)unchanged and broken down by conventional treatment.
A. They don’t easily degrade or dissolve in water. His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs.
B. And manure contains especially high levels of bugs that are resistant to antibiotics, he says.
C. Animal antibiotics is still an area to which insufficient attention has been paid.
D. But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people.
E. His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal feed.
F. They could also be leaching(过滤;萃取)into tap water pumped from rocks beneath fertilised fields.
G. There is no doubt that the food and drink is always important to the health.
【R1】
选项
答案
E
解析
本句中包含he这个代词,故上文中必定有它的先行词,his findings又表明此人应该是从事科研工作的,句中又提到Switzerland,考虑这种种因素,填入E是正确的。
